Abstract

A cleaning composition comprising a choline salt and a surfactant or solvent. Also, a method of cleaning using the cleaning composition.

Description

CLEANING COMPOSITIONS OF HILL SALT FIELD OF THE INVENTION The present invention relates to choline salts in cleaning compositions.

BACKGROUND OF THE INVENTION The elimination of hard food remains through easier, faster means is a continuous goal in dishwashers. Most attention historically has been given to pure fat soils. Also, the need for daily cleaning is easily met by conventional cleaners and cleaning equipment. The removal of heavily encrusted and burned dirt, however, remains a challenge. Common approaches include prolonged soaking and / or intense scrubbing. Specialized solutions such as pre-treatment products can be generally effective but very abrasive or severe (high pH) on hands and surfaces. Also, they are inconvenient for the consumer since the multiple products are required for complete cleaning. A growing problem comes from the excessive use of microwave ovens that provides more intensive cooking.

It would be desirable to have a cleanser that is effective in hard dirt removal.

SUMMARY OF THE INVENTION A cleaning composition comprising at least 7.5% by weight of choline chloride and at least one of a surfactant and a solvent is provided. A cleaning composition comprising choline bicarbonate, surfactant, and solvent is provided. A cleaning composition comprising at least 0.5% by weight of at least one choline salt chosen from choline salicylate and choline dihydrogen citrate, and at least one of a surfactant and a solvent is provided.

Also, a cleaning method comprising applying the cleaning composition to a substrate, and optionally removing the cleaning composition.

Additional areas of applicability of the present invention will be apparent from the detailed description provided below. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

DETAILED DESCRIPTION OF THE INVENTION The following description of the preferred modalities it is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

The composition includes a choline salt to improve the cleaning efficiency of the composition.

In certain embodiments, the amount of choline chloride is at least 7.5%, at least 10%, at least 15%, at least 20%, at least 25, at least 30%, at least 35%, at least 40%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75% by weight, at least 80%, at least 85%, or at least 90% by weight. In certain embodiments, the amount of choline bicarbonate is at least 1%, at least 5%, at least 7.5%, at least 10%, at least 15%, at least 20%, at least 25, at least 30%, at least 35%, at least 40%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75% by weight, at least 80%, at least 85 %, or at least 90% by weight. In certain embodiments, the amount of choline salicylate and / or choline dihydrogen citrate is at least 0.5%, at least 1%, at least 5%, at least 7.5%, at least 10%, at least 15%, at least 20%, at least 25, at least 30%, at least 35%, at least 40%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75 % by weight, at least 80%, at least 85%, or at least 90% by weight.

The composition optionally contains a hydrogen bond donor for the choline salt. The examples of hydrogen bond donor include, but are not limited to, urea, aromatic carboxylic acids or their salts, salicylic acid, salicylate, benzoic acid, benzoate, dicarboxylic acids or their salts, oxalic acid, malonic acid, succinic acid, glutaric acid, adipic acid, tartaric acid, tricarboxylic acids or their salts, citric acid or its salts.

In certain embodiments, the amount of hydrogen bond donor is at least 1%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, or at least 75% by weight.

The hydrogen bond donor can be presented in a weight ratio with the choline salt in a ratio of hydrogen bond donor to choline salt from 1: 1 to 4: 1. In certain modalities, the ratio is around 1: 1. In other modalities, the ratio is around 2: 1 or about 3: 1.

Choline chloride itself is not a liquid salt since its melting point is significantly above 100 ° C (upper limit indicated by the definition of liquid salt). The combination of urea and choline chloride, however, forms what is called a "deep eutectic solvent" that visualizes properties as a liquid salt in Unusually low melting point terms. The molar ratio of optimal urea to choline chloride, in terms of depression of lower melting point, is reported to be 2: 1, respectively. Surprisingly, it has been found in this research that this deep eutectic liquid also provides effective solvation of firm food soils. In addition, it was found that a 2: 1 weight ratio of urea to choline chloride appears to be optimal in terms of cleaning food. The urea formulated with choline chloride in aqueous solutions ranges from 1: 1 to 4.:1 weight ratio, respectively, providing improved cleaning of food soils above the capacity of the individual ingredients.

In certain embodiments, the composition contains at least one surfactant. In certain embodiments, the amount of surfactant is 0.1 to 45% by weight. In other embodiments, the amount of surfactant is at least 0.1%, at least 1%, at least 5%, at least 10%, at least 15%, at least 20%, at least 25%, at least 30%, at minus 35%, or at least 40% by weight.

The paraffin sulphonates commonly used are those of Ci2-i8 carbon atom chains, and most commonly are of Ci4-i7 chains. Such compounds can be made to specifications and desirably the content of paraffin sulfonates outside the range C 14-17 will be lower and minimized, as will any content of di- or poly-sulfonates. Examples of paraffin sulfonates include, but are not limited to, HOSTAPUR ™ SAS30, SAS60, SAS93 secondary alkane sulfonates of Clariant surfactants, and BIO-TERGE ™ of Stepan, and CAS No. 68037-49-0.

The Organic non-ionic synthetic detergents are generally the condensation products of an aliphatic or hydrophobic alkyl aromatic organic compound and hydrophilic ethylene oxide groups. Virtually any hydrophobic compound having a carboxy, hydroxy, amido, or amino group with a free hydrogen bonded to nitrogen can be condensed with ethylene oxide or with the polyhydration product thereof, polyethylene glycol, to form a water-soluble non-ionic detergent. . In addition, the length of the polyethenoxy chain can be adjusted to achieve the desired balance between the hydrophobic and hydrophilic elements.

The class of nonionic surfactant includes the condensation products of a higher alcohol (for example, an alkanol containing about 8 to 18 carbon atoms in a straight or branched chain configuration) condensed with about 5 to 30 moles of oxide of ethylene, for example, lauryl or myristyl alcohol condensed with about 16 moles of ethylene oxide (EO), tridecanol condensed with about 6 to moles of EO, myristyl alcohol condensed with about 10 moles of EO per mole of myristyl alcohol, the condensation product of EO with a cut of coconut fatty alcohol containing a mixture of fatty alcohols with chains of alkyl ranging from 10 to about 14 carbon atoms in length and where the condensate contains either about 6 moles of EO per mole of total alcohol or about 9 moles of EO per mole of alcohol and tallow alcohol ethoxylates It contains 6 EO up to 11 EO per mole of alcohol.

The further satisfactory water soluble alcohol ethylene oxide condensates are the condensation products of a secondary aliphatic alcohol containing 8 to 18 carbon atoms in a straight or branched chain configuration condensed with 5 to 30 moles of ethylene oxide. Examples of commercially available nonionic detergents of the above type are alkanol Cu- Ci5 secondary condensed with either 9 EO (TERGITOL ™ 15-S-9) or 12 EO (TERGITOL ™ 15-S-12) marketed by Dow Chemical.

Other suitable nonionic surfactants include polyethylene oxide condensates of one mole of alkyl phenol containing from about 8 to 18 carbon atoms in a straight or branched chain alkyl group with about 5 to 30 moles of ethylene oxide. Specific examples of ethoxylated alkyl phenol include, but are not limited to, nonyl phenol condensed with about 9.5 moles of EO per mole of nonyl phenol, dinonyl phenol condensed with about 12 moles of EO per mole of phenol, dinonyl phenol condensed with about 15 moles of EO per mole of phenol and di-isoctylphenol condensed with about 15 moles of EO per mole of phenol.

Also among the satisfactory nonionic surfactants are the water-soluble condensation products of a C8-C20 alkanol with a mixture of ethylene oxide and propylene oxide wherein the weight ratio of ethylene oxide to propylene oxide is from 2.5: 1 to 4: 1, preferably 2.8: 1 to 3.3: 1, with the total of ethylene oxide and propylene oxide (including the ethanol or propanol group terminal) which is from 60-85%, preferably 70-80%, by weight. Such detergents are commercially available from BASF and a particularly preferred detergent is a C10-C16 alkanol condensate with ethylene oxide and propylene oxide, the weight ratio of ethylene oxide to propylene oxide being 3: 1 and the alkoxy content total being about 75% by weight.

The condensates of 2 to 30 moles of ethylene oxide with esters of C10-C20 mono- and tri-de-sorbitan alkazoic acid having an HLB of 8 to 15 can also be employed as the non-ionic detergent ingredient in the composition described. These surfactants are well known and are available from Imperial Chemical Industries under the tradename TWEEN ™. Suitable surfactants include, but are not limited to, polyoxyethylene (4) sorbitan monolaurate, polyoxyethylene (4) sorbitan monostearate, polyoxyethylene (20) sorbitan trioleate, and polyoxyethylene (20) sorbitan tristearate.

Other suitable water-soluble nonionic surfactants are marketed under the tradename PLURONIC ™. The compounds are formed by condensing ethylene oxide with a hydrophobic base formed by the condensation of propylene oxide with propylene glycol. The molecular weight of the hydrophobic portion of the molecule is of the order of 950 to 4000 and preferably 200 to 2,500. The addition of polyoxyethylene radicals to the hydrophobic portion tends to increase the solubility of the molecule as a whole in order to make the surfactant soluble in water. The molecular weight of the block polymers ranges from 1,000 to 15,000 and the polyethylene oxide content may comprise 20% to 80% by weight. Preferably, these surfactants will be in liquid form and satisfactory surfactants are available as grades L62 and L64.

The alkyl polysaccharide surfactants, which may be used in the present composition, have a hydrophobic group containing from about 8 to about 20 carbon atoms, preferably from about 10 to about 16 carbon atoms, or from about from 12 to about 14 carbon atoms, and hydrophilic polysaccharide group containing from about 1.5 to about 10, or from about 1.5 to about 4, or from about 1.6 to about 2.7 units of saccharide (per example, galactoside, glucoside, fructoside, glucosyl, fructosyl, and / or galactosyl units). Mixtures of saccharide moieties can be used in the alkyl polysaccharide surfactants. The number x indicates the number of saccharide units in a particular alkyl polysaccharide surfactant. For one Particular alkyl polysaccharide molecule x can only assume integral values. In any physical sample of alkyl polysaccharide surfactants there will generally be molecules having different x-values. The physical sample can be characterized by the average value of x and this average value can assume non-integral values. In this specification the values of x must be understood to be average values. The hydrophobic group (R) can be linked in the 2-, 3-, or 4- positions before in the 1- position, (thus giving for example a glucosyl or galactosyl as opposed to a glucoside or galactoside). However, the link through position 1-, that is, glycosides, galactoside, fructosides, etc., is preferred. In one embodiment, the additional saccharide units bind predominantly to the 2- position of previous saccharide units. The link through positions 3-, 4-, and 6-may also occur. Optionally and less desirably there can be a polyalkoxide chain linking the hydrophobic portion (R) and the polysaccharide chain. The preferred alkoxy moiety is ethoxide.

Typical hydrophobic groups include alkyl groups, whether saturated or unsaturated, branched or unbranched containing from about 8 to about 20, preferably from about 10 to about around 18 carbon atoms. In one embodiment, the alkyl group is a saturated straight-chain alkyl group. The alkyl group may contain up to 3 hydroxy groups and / or the polyalkoxide chain may contain up to about 30, preferably less than about 10, alkoxide moieties.

Suitable alkyl polysaccharides include, but are not limited to, decyl, dodecyl, tetradecyl, pentadecyl, hexadecyl, and octadecyl, di-, tri-, tetra-, penta-, and hexaglucosides, galactosides, lactosides, fructosides, fructosyl, lactosyls , glycosyls and / or galactosyls and mixtures thereof.

The alkyl monosaccharides are relatively less soluble in water than the higher alkyl polysaccharides. When used in admixture with alkyl polysaccharides, the alkyl monosaccharides are solubilized to some extent. The use of alkyl monosaccharides in admixture with alkyl polysaccharides is a preferred way of carrying out the invention. Suitable mixtures include coconut alkyl, di-, tri-, tetra-, and pentaglucosides and tallow of tetra-, penta-, and alkyl hexglucosides.

In one embodiment, the alkyl polysaccharides are alkyl polyglucosides having the formula 20 (CnH2nO) r (Z) x wherein Z is derived from glucose, R is a hydrophobic group selected from alkyl, alkylphenyl, hydroxyalkylphenyl, and mixtures thereof in which such alkyl groups contain from about 10 to about 18, preferably from about 12 to about 14 carbon atoms; n is 2 or 3, r is from 0 to 10; and x is from 1.5 to 8, or from 1.5 to 4, or from 1.6 to 2.7. To prepare these compounds a long-chain alcohol (R20H) can be reacted with glucose, in the presence of an acid catalyst to form the desired glucoside. Alternatively the alkyl polyglucosides can be prepared by a two step process in which a short chain alcohol (R10H) can be reacted with glucose, in the presence of an acid catalyst to form the desired glucoside. Alternatively the alkyl polyglucosides can be prepared by a two step process in which a short chain alcohol (Cl-6) is reacted with glucose or a polyglucoside (x = 2 to 4) to produce a chain alkyl glucoside. short (x = 1 to 4) which in turn can react with a longer chain alcohol (R 20 H) to displace the short chain alcohol and obtain the desired alkyl polyglucoside. If this two-stage procedure is used, the alkylglucoside chain content short of the final alkyl polyglycoside material should be less than 50%, preferably less than 10%, more preferably less than about 5%, more preferably 0% of the alkyl polyglucoside.

The amount of unreacted alcohol (the content of free fatty alcohol) in the desired alkyl polysaccharide surfactant is generally less than about 2%, or less than about 0.5% by weight of the total alkyl polysaccharide. For some uses it is desirable to have the alkyl monosaccharide content less than about 10%.

The "alkyl polysaccharide surfactant" is intended to represent both glucose and galactose derived from surfactants and the alkyl polysaccharide surfactants. Throughout this specification, the "alkyl polyglucoside" is used to include alkyl polyglycosides since the stereochemistry of the saccharide portion is changed during the preparation reaction.

In one embodiment, glycoside surfactant APG is APG 625 glucoside manufactured by the Henkel Corporation of Ambler, PA. APG25 is a nonionic alkyl polyglucoside characterized by the formula: CnH2n + lO (? ß ?????)

Such ingredients include, but are not limited to, perfumes, fragrances, abrasives, disinfectants, radical scavengers, bleaches, chelating agents, antibacterial / preservative agents, optical brighteners, hydrotropes, or combinations thereof.

The compositions can be formulated into liquid dishwashers, hard surface cleaners, aerosol cleaners, floor cleaners, cuvette bucket cleaners, microwave cleaners, oven cleaners, or any type of home care cleaner . The compositions can be used when applying the composition to a surface or a wash bath, such as dishwashers. Once applied, the composition can absorb on the surface or an article can absorb in the wash to increase the time of cleaning the composition. Due to the increased cleaning efficiency of the composition, less water can be used, resulting in increased sustainability. The composition may result in less scrubbing necessary for cleaning or eliminating the need for scrubbing. The compositions can be used to remove baked food residues from the substrates.

Specific Modalities of the Invention The invention is further described in the following examples. The examples are merely illustrative and in no way limit the scope of the invention as described and claimed. When on the list, Water Control refers to water that is made to have 150 ppm hardness of divalent ions to represent tap water.

The compositions are tested against dirt from common fat-free, hard-to-clean foods. These food stains are starch and egg. Typically, for these difficult food soils, a common consumer practice is to pre-soak food soil in water and dishwashing liquid before regular cleaning of dishes or a surface, such as a stove, before cleaning. The compositions are tested under pre-soaking conditions.

The following procedure is used to make samples of carbohydrate (potato starch) for testing. Potato starch (such as King Arthur potato flour) is mixed in a volume ratio of 1 to 4 with water and mixed in a Braun multi-mixer with a puree mixture until smooth. Leaving the mixture gelatinize. A laboratory scale oven (such as convection or IR) is pre-heated to a temperature that correlates to a temperature of 176.7 ° C (350 ° F) up to 204.4 ° C (400 ° F) from a standard domestic oven. 6.5g of starch mixture are placed on a tarred stainless steel plank and baked in the oven for 25 minutes.

The following procedure is used to make samples of egg albumin for testing. White egg powder (such as white powder from the King Arthur egg) is mixed in a volume ratio of 1 to 2 with water. A laboratory scale oven (such as convection or IR) is pre-heated to a temperature that correlates to a temperature of 176.7 ° C (350 ° F) up to 204.4 ° C (400 ° F) from a standard domestic oven. 4g of the mixture are placed on a tarred stainless steel plank and baked in the oven for 12 minutes.

The following procedure is used to soak the tablets in test compositions to determine the amount of dirt that is removed. Establish a constant temperature bath with bucket holding the shelf at 22 ° C (72 ° F). Pour 100 ml of test composition 46 ° C (115 ° F) into a 150 ml cuvette and place the cuvette holding the shelf in a water bath. Carefully slide the test planks into buckets so the dirt side of the floor to lie on the bottom of the bucket. Allow the soiled surface to soak at rest for the determined time (15 or 30) minutes and then throw the tablets out and rinse briefly. Leave the tablets to dry overnight. Weigh the planchets to determine the percentage by weight of the dirt removed.

The following tests are used to determine the relationship of change variables in the formulas. The trends can be seen in the data presented. For soaking tests, the starting temperature of the soaked composition is provided. The temperature is not maintained at the starting temperature as the composition is at a room or room temperature.

The impact of surfactants on choline chloride in% aggregate cleaning of the combination against surfactant alone in elimination of egg albumin after 30 minutes of soaking at 46 ° C. The choline chloride is 25% by weight and the surfactant is 2% by weight. The composition is neutral pH. Numbers in parentheses shows the actual% of dirt removed by the combination and the surfactant alone) The impact of choline chloride with different solvents on the elimination of egg albumin after 30 minutes of soaking at 46 ° C. PEG 600 is polyethylene glycol with 600 of molecular weight.

The formulations below can be applied as spray products in pump and low viscosity aerosol spray.

Alternatively, it can be modified as necessary with salts, surfactants, polymers or other thickening agents to produce moderately to highly viscous liquids, wash gels or gelled liquids that can be poured or cleaned on a soiled surface. The treatment can be used on bakeware, conventional surfaces or microwave ovens, cooking surfaces or other cooking device that has been stuck with food waste. They are distinguished from the dish detergent formulations described below in that they contain none or low levels of surfactant and are therefore very suitable for removing protein, carbohydrate and fat-derived stains from other hard surfaces such as kitchen floors, bathtubs. / shower cubicles, sinks and toilet bowls. Consumers want low-foam products that require minimal rinsing for these tasks. These formulas contain choline chloride and additionally contain a mixture of one or more co-solvents for improved performance. The solvent in these formulas is ethanol. When spraying onto soiled surfaces, the solvent portion of the formula quickly evaporates > / = 20 ° C temperature, and the remaining, essentially non-volatile liquid salt becomes more concentrated for the improved disposal of specific soils. The formulation may additionally contain a mixture of one or more surfactants and other co-solvents (water, propylene glycol, etc.) for improved performance. The formulations show effective cleaning when applied generously (dirt equivalent weight) in net concentration to a dirty stainless steel substrate that is then rinsed gently (without physical agitation) with room temperature water after 15 minutes of time to remove debris from loose dirt. The formulations with high alcohol content generally do not carry out eliminations of carbohydrate soils since this type of dirt needs sufficient hydration and swelling to facilitate its elimination. Formulas high in choline and reduced alcohol do not provide this mechanism and are found to effectively clean both types of dirt components.

The following formulas contain choline chloride and additionally contain solvents (water, propylene glycol, etc.) as well as one or more surfactants. Additionally, these formulas contain one or more hydrogen bond donors (such as urea or citric acid), which provide improved performance at reduced liquid salt concentrations. These formulations are intended for the pre-treatment of dirt from difficult-to-clean foodstuffs of kitchenware as well as general polyvalent cleaning tasks. They contain low levels of surfactant for formula stability and improved wetting of soils with low foaming profile. The approach has shown efficacy in removing carbohydrate (potato and rice) and protein (egg) soiling at room temperature. Example A in the table below is provided as a dirt cleaning comparison achieved by a 20% choline chloride formulation that does not contain a hydrogen bond donor such as urea. Also, it should be noted that the acid formulations such as formula D in the table below, which contains citric acid as The hydrogen bond donor and resulting formula pH between about 2.5 to 4.5, provides better carbohydrate removal. All other formulas (letters A through C) in this example are approximately neutral pH.

The acidic dish detergents that were formulated contain between 15-33% active surfactants and between 15-30% choline chloride. These acid detergents with pH between 2.5 and 4.5 contain citric acid as a hydrogen bond donor. Citric acid works in these formulas as both the acid buffer and the donor. H link. However, citric acid could be replaced by any of the hydrogen bond donors. Alternatively, sodium citrate or another bond donor could be used in combination with an acid source such as lactic acid, sulfuric acid, etc. with the proviso that the selected H-bond donor is stable in storage in a finished acidic formulation. The table below describes both an acidic liquid base formulation for high surfactant contents frets (Example A) and an acidic liquid base formula for frets of proportionally reduced surfactant content (Example B). Due to the formulation restrictions, the high surfactant formulation is limited to 15% by weight concentrated choline chloride and citric acid, respectively. Whereas, the reduced surfactant formulations are capable / could be formulated with up to 30% by weight concentrated of each material. The cleaning experiments were then carried out with either water (placebo) or choline chloride. In general, the combination of higher choline chloride with reduced surfactant (base B formulas) provides improved cleaning compared to reduced choline with prototypes of high surfactant (base A). Also, significantly better cleaning is observed with choline chloride formulations compared to placebo in more concentrated 10% soaked solution. Whereas, only directionally better cleaning is observed in most cases with choline chloride formulations compared to placebo under standard soaking conditions 0.27%. Also, it should be noted that the removal of carbohydrate is improved with acidic formulations, in general, compared to neutral or basic formulations shown below. The more concentrated prototype solutions provide greater damping capacity and, in this case, provide and maintain a more acidic soaking solution.

Neutral dish detergents were formulated containing between 11-27% active surfactants and between 15-30% choline chloride. These detergents of approximately pH range 6-8 contain urea as a hydrogen bond donor. The urea can alternatively be replaced by any of the link donors of hydrogen. Preferably this material would be pH neutral or could be neutralized by a sufficient amount of either acid or alkaline source to produce a stable finished storage formula of approximately neutral pH. The table below provides examples of both a neutral liquid base formula for high surfactant content frets (example C) and a liquid base formula for reduced surfactant neutral content plate (example D). Choline and urea were formulated at the highest possible concentrations in the respective surfactant bases and formulated in a 1: 1 weight ratio. However, it is possible to formulate up to a 4: 1 weight ratio of urea: choline chloride to provide improved cleaning of food soils beyond formulations with each of these materials alone. The cleaning experiments were then carried out with either water (placebo) or choline chloride. Significantly better cleaning is observed with formulations of choline chloride compared to placebo in concentrated soaked solutions and at least directionally better cleanliness is observed compared to placebo under standard soaking conditions 0.27%. While acidic liquid dish formulas are described above, they are particularly effective in removing carbohydrate-based soils, liquid formulas for neutral dishes They are particularly effective in removing protein-based dirt. These cleaning benefits are most noticeable with the superior choline chloride / reduced surfactant options (B & D formulas) which are the most preferred among the first generation prototypes.
